What is the 25-Mile Isolation List?

Just as 2000' is an important prominence threshold and 14000' an important elevation threshold, 25 miles is the magic number that gives a peak a spot on an isolation list. This page contains those peaks with 25 miles of isolation which are in the U.S. State of Colorado. But what is isolation anyway? Isolation is how far a peak is from the nearest higher one. Understandably, isolated peaks are often also high in elevation, are very topographically prominent, or, in some cases, both. Colorado is no exception as the state's highest and most prominent peak is also its most isolated, and, indeed, all of the peaks on this list, except two, are also on the Colorado 2KPs page, and every single one is over 9000' in elevation, and most are over 12000'.

Contained below is a table containing the peak's name--which has a hyperlink to the peak page--as well as its isolation, elevation, and topographical prominence. So, without further ado, the Colorado
isolation list.

Mount Eolus vs. Windom Peak

Although the listed elevations sometimes indicate the opposite, I have been informed that Windom Peak is indeed higher than Mount Eolus. Despite what other pages on this site and elsewhere might say, Windom Peak is truly the higher of the two, meaning it, not Eolus, should be on the Colorado 2KPs page and should be ranked higher than it is on the various 14er pages. Thanks to SPer Scott for the update.
